LESTER S. GUNDERMAN, OF PITTSBURGH, PENNSYLVANIA MECHANICAL 'IOY.

Application filed March 25, 1925. Serial No. 18,111.

To all whom it may concern.

Be it known that I, Lns'rnr. S. Gunman- MAN, a citizen of the UnitedStates, residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMechanical Toys, of which the following is a specification.

This invention relates to an improvement in an automatic toy having atipping track of a loop the loop type. V

The object of this invention being to provide a mechanical toy in whicha miniature vehicle is raised from-a lower level to a higher level fromwhich it runs by force of gravity downward, through a double loop to theopposite end of the track, from whence it is again elevated to gravitateback to its initial position.

In the accompanying drawing;

Fig. 1 is a top plan View of the improved toy.

Fig. 2 is a section on line X-X Fig. 1 and shows the parts in oneposition.

Fig. 3 is a plan view of the end of the track showing the openings forretaining the rolling object.

Fig 4f is a section YY Fig. 1 of the track showing the separable jointsin the track.

Referring to the drawing 7 designates the supporting base. Secured tothe base are two uprights 8, and supported in the two uprights is atransverse shaft 9. Pivoted on this shaft by means of cars on the underside thereof is a frame 11 secured to the track section 12. Spaced aparton the track is a pair of loops 13, the track and loops being anintegral part thereof. The ends of the loop track are provided with apair of parallel slots 14 into which tongues 15 of the loose tracks 16fit in such a manner as to form firm detachable joints. The entire trackcomprises three sections 16, 16 and 12 joined together and supportedabout mid way between its end on frame 11 which is pivotally connectedto the uprights 8. This track is made in section to minimize the spacefor packing the toy.

Near the outer end of the removable track sections are a pair ofparallel slots 17 for retaining the rolling object 18 until thepredetermined height is reached for the rolling object to gravitatetherefrom. object is shown here as a miniature car which may be of anyconventional type.

The rolling The spring motor 22 forming apart of this toy, may be of anyapproved design.

The operation of the toy may now be de-1 scribed assuming the rollingobject to be in a position as shown in Fig. 2, the object is about toleave the slot 17 and descend the abrupt incline port-ion of the track,then around the first loop then descending the middle incline tracksection, the object gathers momentum enough to carry it around thesecond loop and to the opposite end of the track where it is retaineduntilv the track end is elevated by the rotation of the motor when theobject will gravitate in like manner back to the starting end of thetrack to again be elevated, repeating the operation during the runningof the toy.

I claim 1. A toy comprising a tilting track having reverse inclinedsurfaces, the said track being pivotally supported therebeneath betweenthe ends thereof and so shaped as to have two loops positioned one oneach side of the pivotal support, and an object adapted to roll on saidtrack by gravity.

2. A toy comprising a tilting track pivotally supported therebeneath andarranged to alternately elevate the end thereof, a pair of loopspositioned between the ends of the said track the said loops being anintegral of the track, a. pair of parallel slots at each end of thetrack, and an object adapted to travel in the said tracks by gravity andbe received in said slots.

3. A toy comprising a tilting track pivotally supported therebeneath andarranged toalternately elevate the ends thereof, the said trackincluding a pair of loops each spaced equal distance from the said pivotsupport, the ends of said track having upwardly inclined surfaces, andmeans for giving a rolling object added momentum for passing through theloop to the opposite end of the said track.

4. A toy comprising a base, a pair of up rights mounted on the saidbase, a tilting track pivotally mounted therebeneath on the line witheach other. I

said uprights, a pair of loops each spaced equal distance from the saidpivot support, means for positively tilting the track to alternatelyelevate the ends anda-n object adapted to travel on the track bygravity, the ends of the said track being so arranged that the objectwill be elevated from a lower level to a higher level, to gravitate tothe opposite end of the track.

5. A toy comprising a tilting track pivotally supported therebeneath andarranged to alternately elevate the ends thereof, the said trackincluding a pair of loopseach spaced equal distance from the said pivotsupport the outer ends of the loops having a pair of parallel slotsspaced back from the ends thereof, the outer sections of the trackhaving a pair of parallel. lugs bent downward below; the surface of thetrack and extendinto the slots in the loop sections, the end portionsof; the lugsresting underneath the track to assist in holding saidsections in 6. A toy comprising a tilting track pivotally supportedtherebeneath the said track including a, pair of loops each spaced anequal distance from the pivot support the end of track having upwardreverse inclined surfaces, and arranged to alternately elevate the ends;thereof, and power driven means for continuously rocking the trackduring the operation of the toy, and a rolling object adapted to travelon the track by grav-i ity and be transferred from one end of the trackto the opposite end by the motion of; said tracks.

'2'. A toy comprising a, reverse inclined track pivotally supportedtherebeneath, a pair of loops each equally spaced from the pivot supportthe said loops being an integral part of the track, a driving armcarried on the said track and extending downward from the said pivotsupport, the lower end of the said arm carrying a pivot bearing,'aconnecting bar pivotally mounted on the said arm the opposite end of theconnecting bar being pivoted to means for driving the same, said arm andconnecting bar including pivot bearings and driving means, beingarranged to alternately elevate the ends of the track and an objectadapted to gravitate from one end of the track to the opposite end bythe elevating of said track.

8. A toy comprising a tilting track pivotally supported therebeneath, apair of loops each spaced an equal distance from the pivot support, thesaid loops being an integral of the said track, the outer ends-of theloop section having :a pair of parallel slots spaced back from theendsthereof, the outer end sections of the track having a pair ofparallel lugs bent downward below the surface of the track and extendinginto the slots in the loop section the end portions of the lugs restingunderneath the track, the outer ends of the removable sections beingprovided with apair of parallel slots for retaining the rolling objectuntil elevated by the tilting of the track, the rolling object beingtransferred from one end ofthe track to the other by gravity.

In testimony whereof I aflix my signature LESTER S. GUNDERMAN.
